Bullpup pump shotguns seem to be all the rage these days, with their ability to carry upwards of a dozen rounds in a dependable, hand-operated action.
In particular, the DP-12 Shotgun is interesting because it offers two independent firing systems; that is, it has two 7-round magazine tubes and two barrels—a double-barrel pump gun.
Connecticut Shotgun Manufacturing Co., doing business as Standard Manufacturing LLC for purposes of making the DP-12, is a double-barrel shotgun maker, but more along the lines of premium break-open models, such as Winchester Custom Shop Model 21s and A.H. Fox shotguns.
What Standard Manufacturing has done is marry the pump shotgun with the single-trigger double-barrel shotgun, markedly different than other entries such as the KSG and the UTS-15, which employ a single barrel fed by two separate 7-round tubes.
As shown in the accompanying video, the receiver for the DP-12 is machined from a solid block of aluminum, making it super stout. Because of the weight of its mechanical systems and the number of rounds it carries, the DP-12 fires from the shoulder much like any other pumpgun.
As shown, the shooter chambers two rounds with each pump; then pulls the trigger two times, the first to fire the right barrel, the second to fire the left barrel. Pump, bang, bang. Pump, bang, bang. Repeat as necessary.
A number of rails up front allow for placing lights or other accessories. The barrels are threaded for adding chokes or breaching muzzle brakes, and the safety location is standard AR placement.
The unconventional timing of pulling and firing is a learned skill at the range, but the rhythm isn’t that hard to master. Pau J. Corsi, CAD designer from Standard Manufacturing Co. LLC, fired 14 rounds in around four seconds; Austin Miller, a reporter from Taylor Made Media, wasn’t quite as fast, but he did adapt pretty quickly. Part of that is understandable — there is no way to be faster with a follow-up shot than just pulling the trigger. We could fire the second shot the instant the trigger reset.
The pump was easy to run. The ridged forearm keeps the pump hand from sliding forward.
Conclusions: We probably wouldn’t want to carry this gun to on long treks, but as a house-defense solution with one tube loaded with buckshot and the second tube with low-recoil slugs or birdshot, as your situation dictates, the DP-12 brings a lot to the table.
